Using Z-Push on Windows

I tried to install and run on Windows with nginx and fastcgi.
After a lot of hours a made it run with version 2.3.9, but very unstable. Very often it seems that it kills php-cgi.exe.
It is still running, but php content is not responding anymore.
Also a lot of warnings and errors as listed below occured:

Not possible to determine class of request. Request did not contain class and apparently there is an issue with the HierarchyCache.

SimpleMutex not available as InterProcessData is not available. This is not recommended on duty systems and may result in corrupt user/device linking.
